jsp實(shí)現(xiàn)仿QQ空間新建多個(gè)相冊(cè)名稱(chēng)并向相冊(cè)中添加照片功能
熱門(mén)標(biāo)簽：企業(yè)怎么在聯(lián)通申請(qǐng)400電話 如何用中國(guó)地圖標(biāo)注數(shù)字點(diǎn) 南昌市地圖標(biāo)注app 聊城智能電銷(xiāo)機(jī)器人外呼 南京新思維電話機(jī)器人 地圖標(biāo)注市場(chǎng)怎么樣 百度地圖添加標(biāo)注圖標(biāo)樣式 好操作的電話機(jī)器人廠家 泰州泰興400電話 怎么申請(qǐng)

工具：Eclipse，Oracle，smartupload.jar；語(yǔ)言：jsp，Java；數(shù)據(jù)存儲(chǔ)：Oracle。

實(shí)現(xiàn)功能介紹：

主要是新建相冊(cè)，可以建多個(gè)相冊(cè)，在相冊(cè)中添加多張照片，刪除照片，刪除相冊(cè)，當(dāng)相冊(cè)下有照片時(shí)先刪除照片才能刪除相冊(cè)。

因?yàn)槊總€(gè)相冊(cè)和照片要有所屬人，所以順帶有登錄功能。

聲明：只是后端實(shí)現(xiàn)代碼，前臺(tái)無(wú)任何樣式，代碼測(cè)試可行，僅供參考。

代碼：

數(shù)據(jù)庫(kù)連接幫助類(lèi)：

public class JDBCHelper { 
 public static final String DRIVER = "oracle.jdbc.driver.OracleDriver"; 
 public static final String URL = "jdbc:oracle:thin:@localhost:1521:xxxx"; 
 public static final String DBNAME = "scott"; 
 public static final String PASSWORD = "xxxx"; 
 public static Connection getConn() throws Exception{ 
 Class.forName(DRIVER); 
 Connection conn = DriverManager.getConnection(URL, DBNAME, PASSWORD); 
 return conn; 
 } 
}

圖片上傳時(shí)，要修改圖片名稱(chēng)，防止上傳重名圖片將上一張覆蓋，這里的做法是將圖片名改為由用戶(hù)ID和精確到毫秒的時(shí)間組成，修改圖片名的幫助類(lèi)：

public class PhotoName { 
 private String ip; 
 public PhotoName(String ip) { 
 super(); 
 this.ip = ip; 
 } 
 public String getIp() { 
 return ip; 
 } 
 public void setIp(String ip) { 
 this.ip = ip; 
 } 
 public String getTime(){ 
 Date date = new Date(); 
 DateFormat df = new SimpleDateFormat("yyyyMMddHHmmssSSS"); 
 return df.format(date); 
 } 
 public String getPhotoName(){ 
 return this.ip + this.getTime(); 
 } 
}

實(shí)現(xiàn)所有這些的接口類(lèi)：

public interface UpDAO { 
 /** 
 * 創(chuàng)建相冊(cè)名稱(chēng) 
 * 
 */ 
 public int creAlbum(AlbumPOJO ap); 
 /** 
 *顯示所創(chuàng)建的所有相冊(cè)名稱(chēng)
